Daikenchuto for Intestinal Dysmotility and Prevention of Postoperative Paralytic Ielus After Pancreaticoduodenectomy

Phase 2
Conditions
Paralytic Ileus
Interventions
Drug: Oral/enteral placebo solution
Drug: Oral/enteral TJ-100 solution
Registration Number
NCT01607307
Lead Sponsor
Wakayama Medical University
Brief Summary

A multicenter randomized-controlled trial of daikenchuto (TJ-100), a traditional Japanese herbal medicine (Kampo), to investigate its effect on intestinal dysmotility and for the prevention of postoperative paralytic ileus.

Detailed Description

Daikenchuto (TJ-100), a traditional Japanese herbal medicine, is used for prevention and treatment of postoperative ileus. TJ-100 extract powder (Tsumura \& Co., Tokyo, Japan) is manufactured as an aqueous extract containing 2.2 % Japanese pepper, 5.6 % processed ginger, 3.3 % ginseng, and 88.9 % maltose syrup powder. A recent randomized, parallel-group, double-blind, placebo-controlled, dose-response trial demonstrated that TJ-100 accelerates colonic transit time, particularly in the ascending colon. Given its potential actions in the intestinal tract, it seems reasonable to postulate that TJ-100 may play a role in improving and preventing bowel dysmotility. This study was designed to investigate the effect of TJ-100 on intestinal dysmotility and for the prevention of postoperative paralytic ileus in patients undergoing pancreaticoduodenectomy.

The primary endpoint is the incidence of postoperative paralytic ileus. Secondary endpoints are QOL assessment by the Gastrointestinal Symptom Rating Scale (GSRS) Score (Japanese Version) and visual analogue scale, the change in ratio of abdominal circumference, the incidence of postoperative complications, the length of hospital day, and the incidence of surgical site infection. Two hundred patients are required for the study (100 patients per group).

Primary Outcome Measures
NameTimeMethod
The duration until the first flatus after surgery.14 days

The first passages of flatus will be confirmed by patients themselves and they will inform it to the medical staffs.

Incidence of postoperative paralytic ileus (including the duration of paralysis)72 hours

Delayed passage of first flatus for 72 hours (3.0 days) after surgery, or a postoperative condition that requires an intervention for the ileus. Every 12 hours is counted as 0.5 postoperative day and every 24 hours as 1.0 postoperative day.

Secondary Outcome Measures
NameTimeMethod
Abdominal pain and abdominal distention scores on the Visual Analogue Scale.3 days

Abdominal pain and abdominal distention scores on the Visual Analogue Scale on postoperative day 3.

The long term incidence of postoperative ileus after surgery.2 years

The follow-up investigation of the long term incidence of postoperative ileus is scheduled in two years after surgery.

QOL assessment by the Gastrointestinal Symptom Rating Scale (GSRS) Score (Japanese Version)7 days

QOL assessment by the Gastrointestinal Symptom Rating Scale (GSRS) Score (Japanese Version) on postoperative day 7.

The incidence of postoperative complication.14 days

The incidence of postoperative complication based on Dindo's classification.

The incidence of surgical site infection.30 days

Intra-abdominal abscess was defined as intra-abdominal fluid collection with positive cultures identified by ultrasonography or computed tomography associated with persistent fever and elevations of white blood cell counts.

The change ratio of abdominal circumference.3 days

The change ratio of abdominal circumference on postoperative day 3 and operative day just after surgery

The length of postoperative hospital day.30 days

Patients were discharged only when they fulfilled the criteria as follows: a return to preoperative activities of daily living, no deep-site infections, normal laboratory data, no drains, and the possibility for oral nutrition above the basal metabolism.
